CMH spectrum is much more full than COB spectrum, LEDs do not have full spectrum no matter what(that's why that spectrum chart for this light is a targeted spectrum), even white LEDs are colored LEDs that are coated with phosphor to make them appear to be full spectrum when they are not. Just read this article if you don't believe me about LEDs never having a proper spectrumI just bought mine for 2 major reasons. They give off white light, which I prefer growing my plants under. Also they don't use much electricity.
I have recently used 315w cmh. I found the daylight lamp's spectrum to be better than the agro lamp's spectrum. I think the plants get more energy from daylight spectrums, than they do from lights with loads of red in.
If I did a side by side, I reckon I'd yield more with the cmh daylight lamp, than I would with the 'so called' flowering lamp.
Anyway, the Budmaster cob spectrum does appeal to me.
